Table saw dust extruction problem

[The brighton Carpenter]

Hi All
please help, I'm the proud owner of the CMS table saw module using the ts55 saw. My problem is connecting the top hose to the saw cover it seems an unstable connection being just a push fit that falls apart as soon as the work piece pushes against it! This being another problem the hose being in the way? I do have the hose broom but really don't want to take this with me when working on site. Am I missing an connection?
My first post nice to meet you all.

welcome to the fog barry.
are you saying that the hose going to the crown guard keeps on falling off . as far as i know (i dont have a cms) the hose end (of the special hose arangment) just pushs on. the middle of the hose should be cliped onto the side of the cms unit so the material doesnt hit it  adn pull it off the crown guard.

Hi Alan
Thank you for your prompt reply, I'm not that good at expressing myself that well so excuse me. I'm talking about the hose that connects to the perplex saw cover which has an oval connection, the hose being round is really not going to work.

i thought that was the problem. i presum the hose end is new adn tough. as it wears it will become easier to get on there. it is a design flaw thow. it should be round like the rest of the tools.
if it was me i would make a whip tail(short piece of hose ) and leave it on there (get it well on there)  so you dont have to put it on and off all the time. with the whip tail you will be able to disconect it from the hose end adn leave the other end on the saw. 

im sure other members will chim in that have the cms adn offer a solution

Hi to both Barry and Alan,

Many Festools designed to use the 27mm AS hose use the oval connections.

With all due respect to my learned colleague Alan, these oval dust ports are not a design flaw. When used as intended, in many circumstances the oval port hold the 27mm end fitting better than would a larger round port.

Of course there is a learning curve about connecting the 27mm hose to the oval dust ports. But then, most aspects of the Festool System has a learning curve.

Festool has many thrilled CMS customers who routinely use the Track Saw (TS) module. On trips to Europe and Australia I have used this set-up. Of course at the moment on the router module for the OF1010 and OF1400 is sold in North America. None of the TS modules I used were brand new, so probably the 27mm hose end was conditioned to stay in place with the oval dust port. The same thing happens with the OF1010 router and Domino 500. My own approach is to only connect "veteran" 27mm hoses to those oval dust ports. This works for me because I own a lot of Festool hoses. I can see with a new Festool vac the 27mm hose will be new. Time and use will make the system work as designed.

Morning ,
              the hose may be difficult to connect if it is the grey non AS type . The fittings on my CS70 hoses are harder and less flexible than the ones on my green hose .
Also you need a hose clamp to hold the crown guard hose up in the air so that it is clear of the timber going through the saw, and so that its not pushing or pulling the riving knife sideways. On the cs70 I managed this by feeding the hose through the saw frame so that it looped up in the air . (I need to order the hose clamp.)

Hi Barry

I am sorry that I have only just spotted this thread.

When I received my 'Y' dust hose for the CMS-TS unit I was a little worried about getting the end of the 27mm part pushed into the blade guard. To be on the safe side I warmed it up a little and it went in with no problems. Initially mine came out once or twice but only because I had not pushed it in quite enough. I found that it helps a lot to get the support clip (that secures the 27mm section of hose to the side of the CMS base) in the right place so that it supports the hose and relieves the strain on the connection to the blade guard.

I have attached a photograph of my setup.

If you have any further problems please let me know and I will do what I can to help.

Dear Peter
I can't thank you enough I've been wondering what I was do with the black connector having no instructions! Your photo and description made it all very clear as the clip now holds the hose clear of workpiece and the hose more securely to the saw cover. So once again thank you Peter.

Dear Barry

Great. I will help anyone if I can - there are a lot of other people here on the FOG with just as much to offer.

design flaw might be a bit harsh but it is definetly a design iregularity. it makes no sence to have an odd shaped dc port on some tools.

Hi Alan

I know that you do not have the CMS-TS otherwise you would understand...

If one had a round hose connection the blade guard would have to be much wider which would reduce the dust collection capability above the table. The design works as is and I have no problems with it at all. It just needed to be set up correctly in the first place. There is no risk of damage to the hose end, it stays in place and it sucks up the dust perfectly.

i am completely confused. if the crown guard is about the fence than it can the as wide as it likes  up there. they could have put a round dc port on there and still left the guard the same width. .
every thing i was taught about dust colection contradicts having a oval shaped port. the last thing you want to do is reduce the area of the pipe.

 

[Stone Message]

The very slight reduction in area caused by squeezing the end of the hose would not make a huge difference given the high suction of the Festool extractors. However, if the guard is made wider to accommodate a circular hose connection then the area under the guard would increase in far greater proportion to the reduction just mentioned.

Anyway, try it - it works and works brilliantly.

if the area of the bottom of the guard wa increased then yes dc would suffer but why would you widen the guard. .
i have played with my dc system and my anamometer and you would be suprised at the drop in air speed when the hose is squashed a bit
